Assessment of Various Reciprocating System in the Extrusion of Debris from Curved Root Canals: An Original Study.

Introduction: The endodontic preparation depends largely on the file systems that are used in the canal preparations. The amount of the intracanal debris that is extruded from the apex may be influenced by the file systems. Hence, the present in vitro study evaluated the amount the debris that is extruded for the two file systems at different working lengths. Methods: Forty human mesiobuccal canals of the first molars were collected that were extracted for various causes. They were equally divided to four groups of Reciproc (full length), Reciproc (short by 1 mm), WaveOne Gold (full length), and WaveOne Gold (short by 1 mm). Routine crown-down technique was followed for the canal preparation with the intermittent irrigation. The extruded debris was weighed and compared for the significance. Results: The amount of the debris that was extruded weighed similarly in all the four groups with no significant variations. The Reciproc extruded lesser material than the WaveOne Gold. Conclusions: The file systems seem not to affect the debris extrusion irrespective of the files' physical properties. Further studies in a clinical setup are warranted.

Comparative Evaluation of Three-Dimensional Plating Systems in Maxillofacial Trauma: An Original Research.

Introduction: Many advanced techniques and materials have been introduced in the recent years with the advent of the new designing technology. Hence, in our study, we aimed to compare in maxillofacial trauma, the three-dimensional (3D) plating systems. Materials and Methods: We piloted a prospective clinical study among 50 subjects of both genders with mandibular parasymphysis fracture. We compared the 3D miniplates with the two-dimensional (2D) miniplates where the subjects were divided into 2 groups equally. The clinical parameters were compared at different times of follow-up after the surgery. Results: We observed that there was a similar distribution of the genders and the side of the fracture of the parasymphysis. There was a significant difference between the groups for the mouth opening while there was no significant difference for the sensory deficit. The subjects recovered better with the 3D mini-plates. Conclusion: The mandibular fractures can be successfully treated with the 3D miniplates that help in a quick and efficient recovery.
